Composites sheets based on short wool fibres and polypropylene were fabricated by extrusion process. A three-factor two-level experimental design using Taguchi method was applied in manufacturing the composites to explore the contribution of each parameter on mechanical properties. Fire retardant behaviour of the composites with different fibre weight ratios was investigated by horizontal burning test and cone calorimetric analysis without the addition of any fire retardant agent. Reduction of burning rate with increase in the wool fibre content was observed and suitable formulation of the composites was selected for evaluation of mechanical properties. Request Permissions.

Physical & Chemical Properties of Wool Fibre | Part 04

Wool, one of the oldest textile fibres known, has survived the test of time because of its unique natural properties. The basic characteristics wool possessed in the Stone Age era, for instance, are still the fundamental qualities that make wool unique in this 20th century. Today there are many other textile fibres, but as yet science has not been able to produce another fibre containing all the natural properties of wool. Wool remains unique; a masterpiece of design. Wool Insulates Against Heat and Cold. Because it absorbs moisture vapour, wool clothing provides superior comfort in both hot and cold weather. In cold weather even a little moisture on the skin becomes cold, quickly reducing body temperature.

Multi-Functional Properties of Wool Fibre Composites

Protein Crosslinking pp Cite as. The high levels of covalent disulfide crosslinking in keratins strongly affect 1 structural stability, 2 viscoelasticity, and 3 chemical reactivity. This paper briefly reviews recent work on these subjects, with critical emphasis on methods by which chemical and physical properties can be related to inter- and intra-molecular crosslink density in heterogeneous systems like keratins.

Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats , qiviut from muskoxen , hide and fur clothing from bison , angora from rabbits , and other types of wool from camelids. Wool consists of protein together with a small percentage of lipids. In this regard it is chemically quite distinct from the more dominant textile, cotton , which is mainly cellulose. Wool is produced by follicles which are small cells located in the skin.

Physical and chemical properties of wool

Wool is the natural protein fibre obtained from sheep and certain other animals, including cashmere from goats, mohair from goats, angora from rabbits, and other types of wool from camel. It is a multi-cellular, staple fibre. The density of fibre is 1.
